Interface WeightPixel_F32

All Known Implementing Classes:
WeightPixelGaussian_F32, WeightPixelKernel_F32, WeightPixelUniform_F32

public interface WeightPixel_F32
Used to get the weight for a pixel from a kernel in 2D space. The kernel is assumed to be centered around 0 and has the specified radius. The kernel has a width of radius*2 + 1. The information stored inside this interface could be represented as a 2D array, but the interface allows a simple return to be used if the value is constant.
  • Method Summary

    Modifier and Type Method Description

  • Method Details

    • weightIndex

      float weightIndex​(int index)

      Faster way to access the weight. Refers to the index in a row major matrix.

      x = (index % widthX) - radiusX
      y = (index / widthX) - radiusY

      Parameters:
      index - index of grid element
      Returns:
      the weight
    • weight

      float weight​(int x, int y)
      Access the weight using coordinates.
      Parameters:
      x - x-coordinate: range = -radius to radius, inclusive
      y - y-coordinate: range = -radius to radius, inclusive
      Returns:
      the weight
    • setRadius

      void setRadius​(int radiusX, int radiusY, boolean odd)
      Change the kernel's size
      Parameters:
      radiusX - Radius along x-axis
      radiusY - Radius along y-axis
      odd - If odd then the width will be 2*radius+1, otherwise 2*radius
    • getRadiusX

      int getRadiusX()
      Returns the kernel's radius along the x-axis
      Returns:
      Radius of kernel
    • getRadiusY

      int getRadiusY()
      Returns the kernel's radius along the y-axis
      Returns:
      Radius of kernel
    • isOdd

      boolean isOdd()
      If the width is an even or odd number
